What do you say we speed this thread to it's logical end?
Airlines push balanced field numbers into the over runs and weeds with reduced thrust calculations, under the guise that pushing trend monitored engines out to 30,000 hours, saving a few overhauls is worth the risk of flying it to the end, then pulling up.... Combine this with the common hiring practices of picking from the bottom of the resume pile...the most inexperienced pilots they can hire, specifically culled to take orders...a flying marsh-mellow is trained to read a checklist rather then make a decision...he is told to yank the yoke at V1, fly the wreck into the air...because statistically, if your typical pilot flies 'the numbers'..statistically he should be safe..
- unless he gets ice..
- unless he hits a few birds
- unless his seat rolls back to the rear
- unless lightning knocks out his tubes
- unless he has a flight control failure
- unless he has terrorists on board..
etc etc etc....
This philosophy is based on the idea that all scenarios have been addressed in the sim, and put into checklists...which is wrong. It's also under the guise that statistically given a choice under pressure, pilots will screw it up, make a bad decision...this of course is based on some epic mistakes made by airline captains, and certainly doesn't take into account all the non- accidents, famously averted, that never made the news, by pilots who 'thought' their way out of a jam....and many times famously disregarded the checklists that have been written by the lawyers, trying to fight a future court battle, not avert the current impending accident.
So in an effort to control the safety of airline operations, pilots are told to refer to sops and checklists...and secretly hope that nothing will happen out there, outside of the book...which happens all the time....
A pilot sitting there at the end of a 10,000 foot field, purposely moving v1 farther down the field with reduced thrust calculations, knows full well he is increasing the risk of that departure, so do his boss's, so does the FAA. Trying to justify yanking back on the yoke at V1 is really easy when all you ever see in your career at V1 is the end of the runway will building in front of you.
The rest of us have spent a lifetime flying planes where there is a mile of pavement in front of us, and just can't imagine why you'd take the wreck up in the air when you have the opportunity to safely keep the aircraft on the ground.
